Probability evaluation of new hydrocarbon discoveries in selected parts of the Sava and Drava depression, Croatia

In the central parts of the Sava depression, there are some moderately drilled areas with the possibility of discovering minor additional hydrocarbon accumulations near a dozen oil and gas fields. The existence of Pannonian to the Upper Pontian, have been established in the central part of the depression. Two units - IVA and Poljana sandstones - have been isolated in the wider Voloder area. In the Drava depression region the surroundings have also been analyzed. Based on the location of its reservoir, the sediments of the Mosti member lower part have been isolated as a promising unit. Within them, probability has been estimated for the Šandrovac zone. Taking into account the fields existing in the vicinity of these areas, as well as the degree of their exploration, they have been classified as partially well explored. Possible new fields and satellite reservoirs would most probably be in the order of magnitude of the ones already existing in the analysed parts of the Sava and Drava depressions.
